Abstract

A chemically modified and activated, hydroxyl-group-containing, natural or synthetic, polymeric solid body surface is disclosed, as well as a process for the activation of such solid body surfaces by means of organo-silanes and, if necessary, homo- or heterobifunctional reagent. The surfaces are used for the stable, simple and economical binding of proteins, nucleic acids, low-molecular ligands, cells, microorganisms and other biological materials, in biology, biotechnology and medicine.
